Saskatchewan '04

On June 1, 2003 the maximum speed limit on select sections of Saskatchewan twinned highways was increased from 100 km/hr to 110 km/hr.

Data collected at the study sites before the increase indicated that the 100 km/hr speed limit was well below the average driver speed and 85th percentile speed.

Data collected after the speed limit increase showed only a minimal increase in average driver speeds, 85th percentile speeds, and pace speeds, while the average increase in speed differential was found to be minimal.

The speed limit increase appears to have created a higher driver compliance rate, at least in the short term.
